SPECIIFIGATION forming' part of Letters Patent No. 692,860, dated February 11, 1902.

Application filed February 20, 1901. Serial No. 48,109. (No model.)

To all whom, t may concern:

-Be it known that l, CLARENCE M. KEMP, a citizen of the United States, residing at Baltimore,in the StateofMaryland,haveinvented new and useful Improvements in Carbureters,

.of which the following is a specification.

.reting rplant which is peculiarly adapted for use in house-lighting and relates 'not only to the carbureting devices proper, but also to the operating means therefor.

In working out my invention I have borne in mind the necessity of providing such a construction as that the initial cost of manufacture shall beas small as is compatible with structural safety and efficient operation, and, furthermore, it has been my object to so combine the necessary elements which make up the apparatus as to give a very compact construction and one which may be 'packed orv crated for shipping in a comparatively small compass, Ithis being a matter of considerable importance. Again, the construction of carbureter forming the subject-matter of this case is one which minimizes the cost and labor of installation and admits of such a disposition of the devices for carbureting the air relative to the building tobe suppliedas will permit its installation in any place desired, as a special cellar or outhouse is notv essential for the plant and the charging of the same with gasolene is, at the same time, removed from dangerousproximity tothe building to be lighted. The motor mechanism and the air-feeding devices, which are combined with the carbureting devices proper and which form important features of the invention, are simple in operation and easily manipulated, requiring but little attention, after being once'installed to keep them in proper condition to actuate the carbureter and supply air thereto.

In the drawings accompanying and forming a part of this specification, Figure l is a sectionalview, in a vertical plane, of the carbureter and its connected paris, together with the motor mechanism, the latter being in elevation and being broken from and offset relative to the rest of the figure. Fig.v 2

is an enlarged detail pian view of .the motor and its connected parts, portions of the structure being in section tobring the relation of the parts out more clearly. Fig. 3 is a view on line 3 3 of Fig. 2 looking in the direction of the arrow to showthe pawl-and-ratchet connection between the motor and the powertransmitting shaft. Fig. 4 is a detail view of the dipping-wheel which supplies the carbureting device. Fig. 5 is a view in elevation ofthe entire apparatus, illustrating the plant as installed inwerking position.

' Referring to the drawings by numerals, likenumerals indicating like parts in the several figures, 1 indicates a tank or reservoir, preferably cylindrical in cross-section, provided with end plaies Vor caps 2 and having atits upper side an'air-inlet 3. to the tank and surrounding said inlet 3 is a casting 4, which is shown in theA present instance as being inclined to the tank 1, and screw-threaded or otherwise secured in the upper end of said casting 4, which is hollow, is a pipe 5, of considerablediameter, for a reason which will presently appear, said pipe 5 being preferably lined with a non-conducting material and rising in an inclined direction from the tank l, which is to be buried in the ground, as shown, a suitabledistance above thetop of the ground. The inclination of the pipe 5 is of advantage, as thereby the power-transmitting connections from the motor to the driven parts are simplified both in the number of parts and operation,.and, further, in that it provides for a Wide separation of the tank l, containing the gaso- Secured v lene, from the rest o'f the apparatus and val- ICO shaft referred to hereinafter, said casting n at the upper end of pipe 5 and the casting 3, above referred to, serving as bearings for a power-transmitting shaft 7, which will be hereinafter more fully described. Entering said pipe 5 at a point near itstop is an airinlet pipe 8, of any suitable construction, said pipe 8 having at its end a downwardlyturned intake-cone 9, fitted with a strainer 10 to guard against the introduction of foreign substances or accident to the apparatus by fire. I preferably truss or support the pipe 5 by means of a rod 11, secured at one end to a clip or ring 2, encircling the pipe 5 near its upper end, the other end of said rod 11 being secured to the end of the tank opposite that from which the pipe 5 rises.

In one end of the tank l is a storage-compartment which, as shown, is composed of two sections 13 and 14, said compartment 13 being formed by the vertical and horizontal partitions 15 and 1G, while the other compartment 14 is formed with a vertical Wall 17 and an inclined wall 18, the compartments communicating with one another by means of a port 19 in wall 1S, Fig. 1. These two compartments are designed to hold the hydrocarbonsupply,a combined 'filling and vent pipe 2O of any suitable construction being used. Said filling-pipe 2() preferably extends to a point near the bottom of the compartment 13, so as to permit a draining of the supply of oil, if desired, by simply attaching a suction-pump to the top of the pipe 20, which, it will be understood, rises from the tank 1 to a point above the surface of the ground. The compartment 14 is provided with a vent 2l near its top, so as to permit the escape of air from said compartment during filling, the air in compartment 13 escaping through the edges of its top, which is merely a coverand is not air-tight.

The compartment 13 has an outlet-port 22, which communicates with a well or dippingcompartment 23, formed by the vertical parlition 15 and the inclined wall 18, said well forming the receptacle for the supply of hydrocarbon for immediate consumption, which itis desirable to segregate from the main body of liquid in order to avoid as much as possible the agitation of a large body of volatile hydrocarbon, such agitation of a large body of this liquid being objectionable for reasons which will appear hereinafter.

At the other end of tank 1 is mounted a meter-wheel air-pump 24,1 of ordinary construction, said pump having airtrapping members or arms and having its interior fitted with capillary materials, which constantly revolve in the gasolene, are kept saturated, and the gasolene is thereby evaporated and carried off by the air passing through the same, the carbureted air being delivered to the central bore of the wheel and thence to a compartment 25 at the end thereof, into which compartment projects an outlet-pipe 26 for the gas, said outlet-pipe 26 having an u pwardly-turned inner end to carry it above the level of the oil in the tank and passing through the end of the tank 1, so as to connect with a eease stand-pipe 27, from which the distributingpipe 2S leads. The said stand-pipe has a portion 29 depending below the points of connection of pipes 26 and 2S, which is intended io serve as a trap for matters of condensation, and the trap portion 29 may be readily cleaned by attaching a suction-pump to the top of stand pipe 27, which, as shown, projects above the surface of the ground. The said meter-wheel pump 24 is carried by a shaft 30, which is mounted at one end in a bearing 31,

formed at the angle or knee of outlet-pipe 2G,`

(see Fig. 1,) said bearing being preferably a roller-bearing to lessen friction. The other end of shaft 30 is supported in a bearing 32, carried by the vertical wall 18, said bearing being preferably a roller-bearing similar to 31. It will be seen that the bearings 3132 of the meter-wheel shaft are both located inside of the tank and that there is no danger of leakage of gasolene or the volatile gases thereof through the bearings, as is apt to be the case where shafts or other moving parts pierce the Walls of the carbureting-tank. Said shaft 30 carries at its inner end one member of the knuckle-joint 33, the other member of said joint being mounted on the lower end ofthe power-transmitting shaft 7,to which reference has been made, and while I lind this knucklejoint construction admirably suited for the purpose it will be understood that equivalent transmission devices, such as bevel-gears, may be used, if desired. Secured to said powerA transmitting shaft 7 near its lower end and within the tank 1 is a dip-wheel 34, which owing to the inclined position ofshaft 7 rotates in an inclined plane substantially parallel to inclined wall 1S, so that its rim on its upper side over-hangs the vertical wall 17. As the said wheel 34 rotates the rim on the lower side of the wheel dips into the well or dipping-compartment 23, which, as has been stated, contains the small body of hydrocarbon for immediate consumptiomand by means of dipping cups or buckets 35, secured to the rim of the wheel 34, the liquid is dipped from the well 23 and delivered to the meter-wheel compartment as the dipping-wheel 34 rotates. The particular style of dipping wheel and buckets is not material, as this construction may be varied, if desired, without departing from the spirit of my invention. In fact, any suitable device may be used for lifting the oil from the dipping-well and delivering it to the meter-Wheel compartment. It will be apparent that as the meter-wheel is rotated through power-transmitting shaft 7, whose motor connections will presently be described, it will draw in air through the air-inlet pipe 5, which air will pass to the outlet-pipe 26 at the end of tank l after being trapped and enriched in the ordinary manner by the meter-wheel. It is desirable that the air thus drawn in be enriched for the most part in the carbureting-chamber and be not charged with the enriching elements before reaching the said chamber, as would be the case if the IOO IIS

air. passed over a considerablearea ofl hydro-v carbon which was being agitated, vand for this reason the storing of the bulk ofthe hydrocarbon-supply in the closed compartments 13 and 14 and the provision of the well or dipping-compartment 23 between the two is im.- portant, since by this constructiona V-comparatively small body of liquid is exposed and agitated and the volatilization is therefore slight. The dipping-wheel 34 is dished, as shown, in order that it may reach low enough into the well 23 to dip gasolene therefrom at a low point and, furthermore, accom modate a a-trough or oil-chamber 36, which projects from said partition 17 and forms an extension of the pumping-wheel compartment, and being in communication with the said pumpinglwheel compartmentis` always filled to the `Samelevehsothat the bearing 2 iswell lubricated, theknuckle-joint 33 rotates-in oil, and the necessity of a stuffing-box for the shaft which transmits power to the pumpingwheel is done away with. Y

As it is sometimes found desirabletodrain the meter-wheel compartmentfl provide'ak Adrain-pipe 37, which passes downward from the bottom ofV tank 1 and, turning upwardly, rises `above the surface oftheground'in convenient position for the application of-a pump. The power-transmittin g shaft .7. traverses i the air-pipe 54 centrally, a bearing bridge, or spider 37 a being provided in casting 4 to carry andsteadythe lower Vpart of said shaft, its

upper end having itsbearing in a capin the upper endof pipe 3. Said 'power-transmit-- ting shaft 7 is preferablya torsionalA shaft, and I `have foundaconvenient way of making ,it is'to form its removable middle portion 38 0f,-a slender piece of steel, whichA is` round or rectangular in cross-section and which is se-` cured at each end to the end portions of the shaft. The object of providing aA torsional shaft is that when the motor is running and the meter-wheel is being-driven bythepowertransmitting shaft said torsional portion 38 will -be put under torsion,\and if Afor-anyY reason the .motor is momentarily stopped as, for example, during rewindingta-weightmotor being shown in'the present caselthe power stored in the torsionalv shaft will be used in driving the meter-wheel and` there -will be Vno cessation of rotation of thelatter. Furthermore, upon starting the Vmachine the yielding action of the torsional shaft relieves the apparatus of the strain incident toovercoming the inertia of the meter-wheel limmersed in aV body of liquid and an easy startingresulta It will be understood that, if desired, a-torsional coil-springmay be substitutedfor the part 38,*or the entire shaft mayV be .of torsional material, and these equivalent i constructions 1 consider to bewithin the range '.-of my invention. The said power-transmitting shaft 7 is connected at its; upperjend by suitabletransmittingconnections,as knucklejoint 39, with a two-part motor or powershaft mounted in a @frame 40, providejdrwith` suitable bearings 41. f I preferably form said frame 40 integral with one-half of thehead 6, as .shown in Fig. 2, as this vgives a very. strong compact arrangement of parts-the upperend of air-pipe 5 acting as a support for one end of said frame 40, the other end ofthe framebeing supported by suitable standards 42, The two members 43 44 of the two-partdriving-shaft are connected by a ratchet-andpaWl connection, the ratchet member 45 being mounted in the present instance on a hub or pinion 46, keyed to the shaft member43, and the pawl 47 being carried by a large ratchetwheel 48 on the abutting end of shaft mem.-

Vber 44,s,o that the two shaft membersl 43 44 are locked together when the rotation is iny one direction, but when in theother turn independently with the pawl- 47- trailing: idly. The shaft44 is lockedagainst movement in one directionby means of a pawl 49, pivoted .c to theframe 40 and engaging theratchet 4S, u above referred to, thus-preventing the tor.- sional power-transmitting shaft from-,driving theshaftvmember,44-backward when the parts 43 and 44 are disconnected. Mount-ed Y' on the saidshaft member 43 is a circumferentially-grooved winding-drum 51 of-the 0r-` dinary type, which is preferablymounted on roller-bearings 52and'free to'turn on said shaft 43. Said drum has secured thereto or formed integral therewith a gear-wheel 53, which engages a pinion 54 of aback-gea-r.,l mounted on roller-bearings on a stud-shaft` 56 yon the frame, said back-gearing meshing with the pinion 46 on shaftmember 43, so asv to drivethe latterin oney direction when the; weight 57 is wound up, and through the pawland-ratchet connection abovezreferredto the shaft 44 and through'it and the power-transmi'tting shaft 7 drive the dip-wheelh v34.and meter-wheel 24. Y. 1 Whenthe Weight57has -run down and-it becomes necessary to rewind the weight-car#` rying rope on drum 51, a crank or other device is applied tothe squared end of the shaft 43. Rotation fof the shaft 43 will drive .the pinion 4 6, Athe pawl. 47 trailing idly rover' ratchet45, sothat no motion is imparted to shaft 44, said shaft 44 being heldxagainst v backward movement by pawl 49. -The rota-Y tion of pinion 46 is .communicatedto backgear 55 andin turn to the, winding-,druml through pinion 54 and gear 53 and the weight' 57 is drawn up. IfV desi-red or necessary', ahole 5S may be made in the, groundto receive. weight 57, and the.. rope may be run;- ,over a. systeinof pulleys in passing to the drum. L

It is sometimes found desirable -towarm theair beforeit passes .to the carburetiug devices, andv for this purposel provide v`aipipe; 59, running from the stand-pipe 27 and hav-'-- ing-aburner '60 beneathetheair-inlet pipe'i8,-;

so that by'lighting the burner 60'1the airmay-f stated, the airzwilh retain rthe `.heats untilit reaches the carbureting-tank 1.

IOO

I do not wish to be understood as confining my invention to the particular details and features of construction herein shown and described, as I have set forth merely one embodiment of my invention, and it is apparent that the structural features may be varied Within the skill ofthe mechanician without departing from the range of my invention. For lnstance, I have herein shown and described the pipe 5 through which the power-transmitting shaft passes as being inclined; but I do not desire to be understood as limiting myself to such an arrangement of this pipe, for obviously the same may be placed vertically. Having this modification in mind, therefore, I have in some of the claims speciied the pipe 5 as leading upward from the tank. Neither do I Wish to be understood as limiting myself to the precise construction of the air-feed pipe S communicating with the pipe 5, for it Will be obvious that this pipe 8 may lead directly to the tank, or it may be 4dispensed with entirely, in which case the air would be supplied to the tank through the combined filling and vent tube, the cap 20 being left off for the entrance of the air.

In some cases, as where a very cheap apparatus is desirable, I contemplate dispensing with the dipping-Wheel and separate oil-storage'compartment and employing only the airpumping wheel and driving connections, traversing the upwardly-extending pipe 5, as before set forth, and I desire it to be understood that my invention contemplates such a construction of apparatus.
